[Music] until chirp most fishfinders use the single frequency signal considered to be the sonar standard for marking depths as well as fish targets 200 kilohertz is generally considered a good single frequency option for shallow to mid-range depths to around 300 feet and 50 kilohertz is a good option for greater depths although low-rent sonar is considered to be the best fish finder in the world single frequency operation does have its drawbacks for example to increase sensitivity and see more targets you increase flutter on the display both near the surface and in the water column but if you reduce sensitivity to remove clutter from the display you could miss fish targets because chirp sonar uses multiple frequencies within each signal you get the benefit of seeing more fish targets with a less cluttered display better than ever before individual game fish can be clearly identified in
